This paper presents findings from a study of three Zimbabwean science teachers who participated in the Science Education In-service Teacher Training (SEITT) program. At the turn of the century, the SEITT program was designed to develop science and mathematics teachers into expert masters and resource teachers for Zimbabwe’s ten school districts. The study investigated the successes and challenges faced by the three teachers who were in the process of reforming their pedagogical practices as well as writing and using contextualized science curriculum materials to teach secondary science. Data were collected through telephone interviews. The three teachers reported that the SEITT program helped them to transform their practice as well as that of their peers. They also reported that changing their teaching methods motivated learners to actively participate and this change also resulted in improved teacher efficacy. The paper discusses implications for improving science teaching and suggestions for contextualizing the science curriculum in developing countries.
